Thermal decomposition of lutetium nitrate trihydrate Lu(NO3)3·3H2O

Autor: Valdir Aragão do Nascimento, W. R. Guimaraes, Petr Melnikov, Lourdes Zélia Zanoni, I. V. Arkhangelsky, L. C. S. de Oliveira

Publikováno v: Journal of Thermal Analysis and Calorimetry. 131:1269-1276

The thermal decomposition of lutetium nitrate starts with essentially a process of dehydration of the initial monomer Lu(NO3)3·3H2O with further condensation into a hexamer Lu6N18O54·6H2O. The latter decomposes in four steps with release of water,

Publikováno v: Journal of Thermal Analysis and Calorimetry. 122:571-578

The thermal decomposition of dysprosium nitrate is a complex process which begins with the simultaneous condensation of the initial monomer Dy(NO3)3·6H2O into a cyclic hexamer 6[Dy(NO3)3·6H2O]. This cluster gradually loses water and nitric acid, an
